Specification of Letters Patent.

Patented'J 1115 .28, 1914.

To all whom it may concern:

Be it known that we, CHANT A. MILLER and ROYAL V. MILLER, citizens of the United States, residents, respectively, of St. Louis, State of Missouri, and St Joseph, in the county of Buchanan and State ofMissouri, have invented a new and useful Ventilating Device, of which the following is a specification. i

Our invention is a simple, substantial, durable and inexpensive ventilating device used in supplying fresh air and separately removing foul air from sleepin 'car'berths, cars, vehicles, rooms, and the lite at one and the same time, and the objects of our inven-' tion are to soconstruct a device of this class, that c'inders, snow, rain, sleet and the like, will not be admitted, therethrough,v nor cough and cold producing drafts allowed to enter the apartment served thereby, and that dust'particles will be caused to settle in the air admitting passage and chamber,

Further objects are, to 'so arrangeand construct the parts of a ventilator, thatfithe same may be applied as a detachably attached device, or be built in with the body of an apartment, as a'fixture, and also to so construct a ventilator, that the windward end portion of the'same will be warmed by the outgoing air, for preventing the accumulation of frozen moisture on the end and in outside passages; thereby keeping the same'open. Y

Other objects are to so construct a ventilator that the same will offer the minimum amount of resistance to ,the wind and main- .tain the maximum amount of efficiency.

We attain these objects by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a perspective view of the ventilator, showing the inner side, the top and one end of the same. Fig. 2 is a perspective view of the ventilator, with the outer wall removed for exposing the outer air passages and ports. Fig. 3 is a perspective view of the ventilator, in the same-position as seen in Fig. 1,with the inner side and top removed toavoid obscuring the internal parts: Fig.

'4: is an end view, in perspective, of-the ventilator, looking toward-the right. Fig. 5 is a perspective view of the outer side, top, andone end of the ventilator, as it appears when.

in use,in an ordinary car window. Fig.6 is

a view similar to Fig. 5, but showing the ventilatorin use in car roof windows.

Gr, vertical partitlon M, top E, horizontal pa rt1t1o n K and bottom H, form the 'boundaries of the outer air passages .A and B which are open at both ends. The end por-. tions-of partition M are sodeflected that the ends of said outer passages are gradually widened toward their extremities, thus pre- Beferring to Figs. 2 and .3, the outer wall senting greater area to theouter atmosphere for ,forcing .a greater volume of air there- I through.

Referring .:to Figs. 2,3 and 4, port 0 is cut through partition M, at such pointon said partition, theta small part of one of said ncl ned portions and a smallpart of'the' adacent uninclined portion of said partition are thereby removed; which causes'the outer edge of said :port to be farther than the inneredge-o'fsame, from outer wall G. Connected with partition M, at the inner edge of port:C, is1the-tongue.-R, extending inward thereiirom, parallel with said inclined end portion of partition M. Bafiie' plate 0 has its left .end portion curved around the free vertical edge of tongue 1%, at a distance therefrom similar [to the distance between the latter and the said inclined portion of partit on M, theleftedge of said curved portion is connected with said inclined portion of-partition M, while theremainin and flat portion ofjsaid haflie plate exten the right, at a slightly increasing distance from said -,tongue, and terminates at a disztance from partition M, forming communication, therebetween for inner air chamber 3U, and-the return bend airflductVV, which :latter is thus ,formed'; around the sides and ifree end of tongue Bi,-and communicates with ;passage A, throughput-C. Said inner air chamber U is seen between the right portion of Ibafilepl'ate-Oand the deflector L, which chamber rapidly increases in width toward its outer edge, :and opens into said ventizlated compartmenanotshown. Deflector N, ipartition M, tongue S and bathe plate :P, are similarly 1 constructed but arranged reversely to the described parts, for'f0rming air chamber V- and the ret-urnbent air duct T, one end of which communicates with passage B, through ,port D, (see Fig. 2). Said port D is formed in the same manner as the pretoward ioo ;from outer wall "Theseports are thus;

iiarmed :tor influen ing theforcing nd e vhausting of air, through ducts W and T, as hereinafter fully described. Drain opening X is formed through partition M and aifords a small communication between duct l/V and passage B. The inner or front edges of deflectors diverge from each other, forming void between them.

Referring to Figs. 1 and :l, the'inclined plates I and 1' form the upper and lower are adaptedto rest upon the outer portion of the sill of said window, While the lower inclined plate I is adapted to rest upon the inner portion of said sill, for supporting said ventilator, and for providing a weather proof joint between said sill and the bottom of said ventilator.

Referring to Fig. 3, in operation, while the described ventilator is being carried toward the left, the same causes a draft of air to pass toward the right through passage A, and in like manner causes air to similarly pass through passage B. The speed of said drafts is increased when the same reaches and passes through the central, narrowed portions of said passages. Since duct W is inclined toward the same direction that said draft of air is passing through passage A, it is evident .that the same causes air to be exhausted fromsaid ductthrough port 0 and into passage X. Since inner air chamber U, and duct 'form an exhaust conduit, which gradually decreases in width until port C is reached, and since said port is but one half the height of said conduit, it is evident that the current of air exhausted therethrough will be slow of speed and distributed over a cbnsiderable area where the same enters air chamber U, thus pro- -viding an exhaust for foul air from said apartment, without producing sever draft. It will be understood that the air exhausted from said apartment is warmed, and since the same is exhausted through duct WV past the inclined end portion of partition M that said portion is thereby warmed and that said warmth is transmitted therefrom to other parts of the left end of passages A and B, thereby .preventing accumulation of frozen -moisture thereon. Should an appreciable amount of water caused by rain, enter passage A andgravitate from horizontal partition K, through port C onto bottom H, the same would be exhausted therefrom through drain opening X into, passage B,

pands upon reaching the same. said air 1s deflected into and through said and ejected therefrom, into the open air, by the previously described draft of air there through. \Vhile the described exhausting of'air from said apartment is taking place, the draft of air through passage B is being forced past port D (see Fig. 2,) and ex- A part of port by the adjacent deflected portion of partition M. T .e thus deflected air is forced through duct T and inner air chamber V which form a conduit of increasing width which causes the thus supplied fresh air to move slowly from chamber V into said'apartment, without producing sudden or severe drafts. It will be readily understood, that this slow and tortuous move ment of air, causes dust particles to settle therefrom, in said duct and chamber, onto bottom H.

It willbe seen in Fig. 2 that the outer edge of port 1) is out of alinement with the uninclined central portion of partition M,

a'spreviously described, and it will be understood that the inertia of heavy particles of matter, such as cinders, snow -flakes, and the like prevents thesame from being deflected from their straight course through passage B and thereby prevents the same from being deflected into and through said port, and into said apartment, but are carried out at' the right end of said passage; thus forming what might be termed air-blast separating means by which heavier particles of matter are separated from the air admitted into the served apartment.

Since all of the parts to left of void Q, (see Fig. 3,) are the same v in construction and operation, as the parts at the right of said void, except that the same are reversely inclined to air passages A and B, it is evident that the described operation of the ventilator is reversed while the same is moved towardthe right.

It will be 'seen in Fig. 2, that the separate air passages A and B, with their respective ports C and D, provide fresh air inlet means and foul air outlet m ans that are at all times separated; thus preventing the return into said apartment of any part of the exhausted foul air, and insuring an inflow of pure, fresh air, through the described ventilator.

\Vhile we have shown and described our ventilator in the foregoing manner, with an air exhaust port and an air supply portshielded from direct action of the elements, and with specifically shown and described air ducts leadingfrom said port-s, it is evident that said portsand ducts could be ar ranged in a variety of ways, and be so proportioned and arranged as to adapt the same to be used in various situations, without departing from the spirit of our invention all of which we reserve the right to do.
